In the electrochemical cell:
the emf of this Daniel cell is E1. When the concentration of ZnSO4 is changed to 1.0 M and that of CuSO4 is changed to 0.01 M, the emf changes to E2. From the following, which one is the relationship between E1 and E2
(Given, $$\frac{RT}{F}$$ = 0.059)

1. ${E}_{1}<{E}_{2}$

2. ${E}_{1}>{E}_{2}$

3. ${E}_{2}=0\ne {E}_{1}$

4. ${E}_{1}={E}_{2}$

A hypothetical electrochemical cell is shown below.
A|A+(x M) || B+(y M)|B
The Emf measured is +0.20 V. The cell reaction is:

1. A+ + B → A + B+

2.  A+ + e- → A ; B+ + e- → B

3. The cell reaction cannot be predicted.

4. A + B+ → A+ + B
